When exporting to latex, you end up with
#+name: results--tikz-basic-picture
#+caption: Image created by the LaTeX source code block.
#+results: tikz-basic-picture
#+begin_export latex
\begin{tikzpicture}
\node[fill=green, minimum size=2em] {};
\end{tikzpicture}
#+end_export
Caption for export blocks is not meaningful. So, Org ignores it.

Use special block.
#+name: tikz-basic-picture
#+header: :headers '("\\usepackage{tikz}" "\\usetikzlibrary{shapes}")
#+header: :file-ext (by-backend ('latex 'nil) (_ "svg"))
#+header: :results (by-backend ('latex "value") (_ "raw file"))
#+header: :wrap (by-backend ('latex "figure") (_ nil))
#+begin_src latex
\begin{tikzpicture}
\node[fill=green, minimum size=2em] {};
\end{tikzpicture}
#+end_src
#+name: results--tikz-basic-picture
#+caption: Image created by the LaTeX source code block.
#+results: tikz-basic-picture
